Percutaneous balloon pericardiotomy (PBP) has been performed in people and in a small number of dogs as a treatment for recurrent pericardial effusion with tamponade (PET). We performed this technique on 6 dogs with recurrent PET (5 with heart base tumors and 1 with no identifiable mass). Under general anesthesia and fluoroscopic guidance, a balloon-dilating catheter (diameters 14-20 mm) was introduced percutaneously at the 5th intercostal space through a sheath-introducing catheter, positioned across the parietal pericardium, and inflated 3 times. No dog experienced serious complications. The procedure was considered successful in 4 of 6 dogs. One dog is still alive without recurrence of PET 1 year after the procedure. Three dogs died of unrelated disease without recurrence of PET 5. 19, and 32 months after the procedure. The procedure was not beneficial in 1 dog that was euthanized 9 weeks later because of recurrence of pleural and abdominal effusion thought to be secondary to PET. One dog may have temporarily benefited but developed symptomatic PET 6 months after PBP. PBP appears to be a safe, economical, and potentially effective palliative treatment for recurrent PET and is a reasonable, less invasive alternative to surgery for dogs with recurrent PET, especially effusions caused by heart base tumors and possibly idiopathic pericardial effusion. Premature closure of the stoma is a potential cause for long-term failure and was thought to have been responsible for the recurrence of clinical signs in 2 dogs. 相似文献

A 6-month-old crossbred calf was examined as representative of a herd of calves experiencing dyspnea and death, with few other clinical signs of illness. Physical examination of the calf identified pleural and peritoneal effusion and poor body condition. The calf did not respond to supportive treatment, and necropsy of it and another calf from the herd identified congestive heart failure as the cause of death. Gossypol toxicosis was the cause of congestive heart failure in this herd; the source of the toxin was a cottonseed meal and cottonseed hull ration fed by the owner. 相似文献

Percutaneous balloon pericardiotomy for the management of malignant pericardial effusion in two dogs
M. A. Cobb A. Boswood G. M. Griffin F. J. McEvoy 《The Journal of small animal practice》1996,37(11):549-551
Two dogs with signs of right-sided congestive cardiac failure, due to recurrent pericardial effusion secondary to the presence of intraperi-cardial neoplasia, were treated by percutaneous balloon pericardiotomy. The first patient was euthanased one month after the procedure while the second patient developed ascites as a result of obstruction of the caudal vena cava by the growing tumour and was euthanased 14 weeks after the procedure. In neither case was there a recurrence of a significant volume of the effusion. Percutaneous balloon pericardiotomy represents an effective means of relieving recurrent malignant pericardial effusion, without resorting to thoracotomy. 相似文献

OBJECTIVES: To describe a novel technique for the surgical treatment of idiopathic chylothorax in a dog. ANIMALS: A 6-year-old, male Rhodesian Ridgeback, which presented with a history of reduced exercise tolerance and dyspnea. METHODS: Idiopathic chylothorax was diagnosed. Intermittent pleural drainage failed to resolve the problem. During surgery, extensive pleural fibrosis made it impossible to identify the thoracic duct. A dorsal omental pedicle was advanced through an incision in the diaphragm and into the cranial thoracic cavity to act as a physiological drain. RESULTS: The dog recovered well and has remained free from clinical signs of recurrence of the effusion (16 months at the time of writing). CONCLUSIONS: The disease-free interval achieved in this dog indicates that this novel technique is worthy of further consideration in the management of idiopathic chylothorax. 相似文献

A 20-year-old gelding Lipizzaner horse was referred for onset of profuse sweating and increased heat on the right side of the head, neck, and thoracic limb. On physical examination, the horse presented tachycardia, muffled heart sounds with a pansystolic murmur, and signs of heart failure such as ventral edema, jugular distention, and pulsation. Ultrasonography examination revealed a bilateral pleural effusion and a large intrathoracic mass extending into the anterior mediastinum, which shifted the heart dorsocaudally. Thoracocentesis revealed serosanguineous fluid indicative of a melanocytic tumor. Thoracoscopy revealed a large dark mass extending into and filling the cranioventral mediastinum. The mass appearance was consistent with a melanoma, and because prognosis was poor, the owner elected euthanasia. A necropsy supported the presence of disseminated melanomas with a greater thoracic mass involving the right cervicothoracic ganglion, leading to clinical signs of sympathetic denervation. 相似文献

A 6-year-old 18-kg (39-lb) spayed female Standard Poodle was referred for treatment of pneumopericardium. The dog did not have severe clinical signs relating to the pneumopericardium, and the diagnosis was made incidentally while investigating the cause of a cough. Computed tomography revealed an air-filled structure consistent with a bulla to the right of the heart base that appeared to communicate with the pericardial cavity Because spontaneous resolution of the pneumopericardium seemed unlikely and cardiac tamponade was a possibility, exploratory thoracotomy was performed. A lobulated bulla was found at the hilus of the right middle lung lobe adhered to the underlying pericardial sac, and a 4-cm-diameter communication from the pericardium to the pulmonary bulla was found. Right middle lung lobectomy was performed, and the pericardiotomy and pericardial opening were sutured. The dog recovered without complications. In previously reported cases of pneumopericardium involving a cat and a dog, the condition resolved spontaneously. In this dog, in contrast, surgical resection of the affected lung lobe with pericardial reconstruction was required for resolution of the pneumopericardium. 相似文献

A 3‐week‐old Pony of the Americas foal presented with a history of respiratory distress presumed to result from Actinobacillus equuli pleuropneumonia and septic arthritis. Failure of transfer of passive colostral immunity was suspected, but not confirmed, based on a history of the foal being separated from its dam shortly after parturition. Transient improvement was noted following thoracocentesis and removal of approximately 600 ml of pleural fluid but progressive clinical signs of congestive heart failure developed. Fibrinous pericarditis with evidence of cardiac tamponade was subsequently diagnosed via thoracic ultrasonography. Early clinical signs of cardiogenic shock were identified and fibrinopurulent exudate removed through a catheter placed with ultrasound guidance into the pericardium. The foal experienced cardiorespiratory arrest during the procedure and died despite resuscitative efforts. Post mortem examination identified extensive hypertrophy of the pericardium, septic arthritis, mild pleural effusion and focal bronchopneumonia. This report details the clinical evaluation, haematology, treatment and post mortem pathology of a foal with Actinobacillus equuli associated fibrinous pericarditis, as well as a brief review of cardiac tamponade. 相似文献

Pericarditis is an inflammation of the pericardium with accumulation of serous or fibrinous inflammatory products. In cattle, it is almost always attributable to a reticular foreign body that has penetrated the reticular wall, diaphragm and pericardial sac. The lead signs of pericarditis are tachycardia, muffled heart sounds, asynchronous abnormal heart sounds, distension of the jugular veins and submandibular, brisket and ventral abdominal oedema. The glutaraldehyde test is an important diagnostic tool because it is positive in >90% of affected cattle. Other common laboratory findings are leukocytosis and hyperfibrinogenaemia (indicating inflammation), and elevation of liver enzyme activity (reflecting hepatic congestion). Radiographs of the thorax and reticulum often show a foreign body cranial to the reticulum. In the majority of cases, massive fibrinopurulent adhesions obscure the cardiophrenic angle, cardiac silhouette and ventral diaphragm.Ultrasonography is the method of choice for diagnosis and characterisation of pericardial effusion. Echogenic deposits and strands of fibrin are seen on the epicardium, and the ventricles are compressed by the effusion. Severe pleural effusion is usually evident. In cattle with distension of the jugular veins and tachycardia, the differential diagnosis includes right-sided cardiac insufficiency attributable to other causes. Distension of the jugular veins without signs of right-sided cardiac insufficiency may occur with obstruction or compression of the cranial vena cava. The prognosis is poor, and pericardiocentesis or pericardiotomy are inadequate methods of treatment. Thus, prompt and humane euthanasia is indicated for cattle with traumatic reticuloperitonitis. Because a definitive diagnosis of traumatic reticuloperitonitis is not always possible based on clinical signs alone, radiography and ultrasonography of the thorax and reticulum are indicated in doubtful cases. 相似文献

Three horses with clinical signs compatible with pleural effusion were examined with diagnostic ultrasound. In one of the three horses, confirmed septic pleural effusion was monitored with ultrasound during a successful treatment regimen. Eficacy of thoracentesis and detection of recurrence of fluid were readily determined. In the second horse, diagnosis of diffuse pleural neoplasia (lymphosarcoma) was made. In the third horse presented for pleural effusion, the effusion was documented and concurrent ascites detected with ultrasound. Carcinomatosis was found at necropsy. Ultrasound examination proved to be a sensitive, noninvasive modality useful in diagnosis and treatment of pleural effusion. 相似文献

A 6-month-old domestic shorthair cat was referred for evaluation of sudden lethargy and tachypnea following ovariohysterectomy. Upon failure of improvement with supportive care, a cardiologist identified congenital tricuspid dysplasia with signs of heart failure. Furosemide, enalapril, and pimobendan were used to reduce clinical signs and improve length and quality of life. 相似文献

An 8-month-old Labrador retriever bitch was evaluated for sudden-onset, progressive abdominal distension. Physical examination revealed an exaggerated inspiratory effort, severe ascites, bilateral jugular vein distension, and hypokinetic femoral arterial pulses. Thoracic auscultation detected tachycardia with muffled heart sounds, without audible cardiac murmurs. Thoracic radiographs identified severe right ventricular enlargement and pleural effusion. The electrocardiogram was consistent with incomplete right bundle branch block or right ventricular enlargement. Echocardiography demonstrated severe right ventricular and atrial dilation, secondary tricuspid regurgitation, and thinning and hypocontractility of the right ventricular myocardium. Left heart chamber sizes were slightly decreased, with normal left ventricular contractility. A diagnosis of arrhythmogenic right ventricular cardiomyopathy was reached, based on the characteristic clinical, electrocardiographic, radiographic and echocardiographic findings, and the exclusion of other causes of isolated right ventricular failure. Treatment effected good control of clinical signs, until acutely decompensated congestive right heart failure led to euthanasia after 4 months. Arrhythmogenic right ventricular cardiomyopathy is a well-described clinical entity in humans, and has previously been documented in 3 male dogs. The condition is characterised by progressive fibro-adipose replacement of right ventricular myocardium, while the left ventricle usually remains unaffected. It should be considered a differential diagnosis in any young dog presented with isolated right heart failure, syncope, or unexplained ventricular tachyarrhythmias. This article reports the 1st case of arrhythmogenic right ventricular cardiomyopathy in a female dog, and highlights its echocardiographic features. 相似文献

O bjective : To review the clinical and diagnostic findings and survival of dilated cardiomyopathy from a large population of dogs in England.
M ethods : A retrospective study of the case records of dogs with dilated cardiomyopathy collected between January 1993 and May 2006.
R esults : There were 369 dogs with dilated cardiomyopathy of which all were pure-bred dogs except for four. The most commonly affected breeds were dobermanns and boxers. Over 95 per cent of dogs weighed more than 15 kg and 73 per cent were male. The median duration of signs before referral was three weeks with 65 per cent presenting in stage 3 heart failure. The most common signs were breathlessness (67 per cent) and coughing (64 per cent). The majority of dogs (89 per cent) had an arrhythmia at presentation and 74 per cent of dogs had radiographic signs of pulmonary oedema or pleural effusion. The median survival time was 19 weeks.
C linical S ignificance : Dilated cardiomyopathy occurs primarily in medium to large breed pure-bred dogs, and males are more frequently affected than females. The duration of clinical signs before referral is often short and the survival times are poor. Greater awareness of affected breeds, clinical signs and diagnostic findings may help in early recognition of this disease which often has a short clinical phase. 相似文献

A hybrid surgical approach and balloon dilatation were performed successfully in a cat with cor triatriatum sinister and clinical signs of congestive heart failure. Left lateral thoracotomy was used to access the heart and cutting balloon followed by standard balloon dilatation were utilized to dilate the perforation in the anomalous left atrial membrane. Clinical signs resolved completely after dilation of the anomalous left atrial membrane. Based upon the outcome of this case, balloon dilatation appears to be a viable treatment option for cats affected with cor triatriatum sinister. 相似文献

A 14 year-old, spayed female Jack Russell terrier with a six month history of weight loss, lethargy, intermittent vomition and diarrhoea was diagnosed as having a chronic impaction of the caecum with mineralised faecal material. Diagnosis was based on the clinical findings and both survey and positive contrast radiographic studies. The diagnosis of caecal impaction was confirmed at surgery and a typhlectomy was performed with the aid of a linear stapler. Histopathology of the caecum confirmed the impaction to have resulted from faecolithlasis. The dog made a full recovery from the procedure, showing no recurrence of the clinical signs until euthanasia three months postoperatively for probable heart failure associated with mitral regurgitation. 相似文献

OBJECTIVE: To identify clinical signs, underlying cardiac conditions, echocardiographic findings, and prognosis for horses with congestive heart failure. DESIGN: Retrospective study. ANIMALS: 14 horses. PROCEDURE: Signalment; history; clinical signs; clinicopathologic, echocardiographic, and radiographic findings; treatment; and outcome were determined by reviewing medical records. RESULTS: All 14 horses were examined because of a heart murmur; tachycardia was identified in all 14. Twelve horses had echocardiographic evidence of enlargement of 1 or more chambers of the heart. Other common clinical findings included jugular distention or pulsation, crackles, cough, tachypnea, and ventral edema. Nine horses had signs consistent with heart failure for > 6 days. Underlying causes for heart failure included congenital defects, traumatic vascular rupture, pericarditis, pulmonary hypertension secondary to heaves, and valvular dysplasia. Seven horses were euthanatized after diagnosis of heart failure; 5 were discharged but were euthanatized or died of complications of heart disease within 1 year after discharge. The remaining 2 horses were discharged but lost to follow-up. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that congestive heart failure is rare in horses. A loud heart murmur accompanied by either jugular distention or pulsation, tachycardia, respiratory abnormalities (crackles, cough, tachypnea), and ventral edema were the most common clinical signs. Echocardiography was useful in determining the underlying cause in affected horses. The long-term prognosis for horses with congestive heart failure was grave. 相似文献

A 5-month-old Holstein heifer had clinical signs of tricuspid valve insufficiency and histopathologic evidence of endocardial fibroelastosis. The calf had a 3-week history of weight loss, abdominal distention, dyspnea, and decreased appetite. Physical examination revealed signs of right-sided heart failure, and a systolic murmur (II/VI) was heard best over the right heart base. Results of cardiac catheterization and echocardiography indicated tricuspid valve insufficiency and right-sided heart failure. The calf was euthanatized after not responding to treatment with penicillin, furosemide, and removal of fluid from the thorax and abdomen. Necropsy findings included multifocal areas of thickening and opacification of the endocardium of the left and right ventricles. Excessive elastic fibers, consistent with fibroelastosis, were seen by use of special stains applied to sections of endocardium. 相似文献

An 8-yr-old male meerkat (Suricata suricatta) presented with sudden lethargy. A globular-shaped heart associated with pleural effusion on chest thoracic radiographs was consistent with congestive heart failure, and echocardiography was performed under general anesthesia. It revealed an Ebstein anomaly, with mild pericardial effusion and marked right heart enlargement. The animal was treated with imidapril chlorydrate. After 4 mo of treatment, thoracic radiographs still showed right-sided cardiomegaly; however, the animal appeared clinically normal. 相似文献

The clinical findings, diagnosis and treatment of 22 cases of canine empyema are reported. Relevant presenting signs were tachypnoea or dyspnoea with pyrexia of variable duration, usually with a history of transient response to antibiotic therapy. Diagnosis was made by radiographic demonstration of free pleural fluid followed by bacterial examination of thoracic aspirates. Treatment consisted of parenteral administration of antibiotics accompanied, in most cases, by removal of the exudate either by aspiration, drainage through an indwelling cannula or thoracotomy. Sixteen dogs recovered from the initial illness. Two of these were destroyed within four months as a result of recurrence and the remaining fourteen survived in good health for follow up periods between six months and seven years after treatment. 相似文献

A 13-year-old, neutered female domestic shorthair cat was presented for sudden respiratory distress following palliative radiotherapy and the combined administration of a single dose of carboplatin for the treatment of recurrent fibrosarcoma. Clinical and radiographic findings were suggestive of pleural effusion. Echocardiography revealed marked right-sided cardiac enlargement associated with tricuspid regurgitation and Doppler evidence of pulmonary hypertension. After 25 days of treatment for congestive heart failure and suspected pulmonary thromboembolism, clinical signs and echocardiographic and Doppler evidence of right-sided cardiac enlargement and pulmonary hypertension had completely resolved. To the best of the authors' knowledge, this is the first report of reversible pulmonary hypertension, likely secondary to pulmonary thromboembolism, in a cat. 相似文献
